To be clear, NIF's ignition is getting more energy out of the fuel than the laser they hit it with put in, but there are other energy drains and inefficiencies in the system that make it nowhere close to break-even fusion energy. That requires building a new machine designed for continuous fusion detonations.
So it's a scientific accomplishment, but not that scientific accomplishment.
